Meanwhile, while the portable terminal 1100 is being charged using the auxiliary battery 1200, the advertisement content may be output. The display size of the output advertisement content may be determined by the estimated time of completion of the charging of the portable terminal 1100. Each may be implemented to be displayed as a different display size.

For example, as the estimated charging time is shorter, as shown in FIG. 18 (a), the display size of the advertisement content is increased so that the user is concentrated due to the exposure of the advertisement. As the estimated charging time is longer, FIG. 18 (b) As shown in FIG. 3, the display size of the advertisement content is reduced to reduce user inconvenience as the advertisement is exposed for a long time.

To this end, the portable terminal 1100 includes a display area location database 1185 for differently assigning display sizes of visual advertisement contents for each time required, and the battery status notification application 1190 corresponds to an estimated time of completion of charging. The display size allocated to the required time is extracted from the display area position database 1185 to display the advertisement content as the extracted display size.

For example, the first display size is allocated and stored in the ad content database 1180 for 1 to 30 minutes, and the second display size is allocated and stored in the 31 to 60 minutes. It is assumed that the third display size is allocated and stored in minutes to 90 minutes, and the fourth display size is allocated and stored in 91 minutes to 120 minutes.

In this case, when the charge completion time is predicted to be 40 minutes, the battery status notification application 1190 outputs the advertisement content as the second display size allocated to the required time from 31 minutes to 60 minutes, and the charge completion time is 82 minutes. If it is estimated in minutes, the advertisement content is output as the third display size allocated in the required time 61 minutes to 90 minutes.
